Sharpening and Care 



 

To sharpen kai knives in the traditional Japanese and therefore professional way, 
we recommend a number of specific ceramic-bonded whetstones. 
Moreover, the range also offers electronic grinders, as well as care accessories 
and blade protectors.

A detailed manual for re-working symmetric and asymmetric blades with traditional Japanese whetstones can be found here.

Electric sharpener

 | AP-0118
 13,8x11,1x10,5 cm 



A nice compact product design, the lightweight of only 875 g and a newly developed sharpening unit with two pairs of ceramic grinding stones are among the highlights of kai’s new electric sharpener.

Its dimensions fit every kitchen. The power cable can be stored in the casing; a cover protects the sharpening unit against dirt. Finger moulds and non-slip feet ensure a secure hold. Because the two pairs of grinding stones are mounted one behind the other, two operations can be done simultaneously. The first pair, of coarse grinding stones, restores the blunt edge; the second pair, of fine stones, polishes the edge to a fine and clean finish.
